H. FRIEDMAN SAMPLER FOR BAGGED MATERIALS Filed May 9, 1938 2Sheets-Sheet 2 ATTORNEYS Patented July 25, 1939 UNITED STATES PATENTOFFICE 6 Claims.

The invention relates to a seed trier and more especially to samplersfor bagged materials.

The primary object of the invention is the provision of a device of thischaracter, wherein through the use of a plurality of springy tinesgrouped about the piercing end of a sampler or trier tube and a gauge,the said tines will be limited in their insertion in the intersticespresent between the strands of a weaved container such as a bag, sack orthe like filled with seed, either grain or other material, withoutexcessive disturbance of the strands or the damaging of the same andconfine the weave at the point of the piercing of the sampler or triertube through .the fabric of the said container, yet allowingdisplacement of the strands of the weave for accommodation of thesampler or trier tube for the entry into the contents of said containerwithout damaging the weave or permanently leaving an opening in thecontainer on withdrawal of the sampler or trier tube therefrom, thesampler or trier tube being for the sampling of the contents of thecontainer in the usual well-known manner in that a quantity of thecontents is taken up and held by such tube for easy inspection thereofon withdrawal from the bagged material.

Another object of the invention is the provision of a device of thischaracter, wherein the sampler or trier tube can be readily and easilyin 30 serted into material within a container such as a bag, sack or thelike to the desired extent for assuring the obtaining of a quantity ofsuch material for its inspection, and such material can be readilytested, not only as to size and condition of the grain, but at anyparticular part or portion thereof and thus arriving at a fair test, thesampler or trier tube when being forced through the container for entryto the bulk of its contents the fabric of such container will bemaintained in approximately the original state of weave yet the strandsbeing susceptible of displacement temporarily for the admission of thesampler or trier tube into the bulk of the contents of said containerand in a manner to eliminate permanency of a hole therein on withdrawalof the sampler or trier tube from the container and its contents and inthis way preserving the weave of the container without resultant damagethereto by the piercing operation required of the sampler or trier tube.

A further object of the invention is the provision of a device of thischaracter, wherein the construction thereof in its entirety is novel,being susceptible of easy handling for the sampling operation thereofand assures against damage to the container through temporary puncturingthereof for sampling purposes.

A still further object of the invention is the provision of a device ofthis character, which is simple in its construction, thoroughly reliableand effective in operation, convenient for application to and removalfrom the work, durable and inexpensive to manufacture.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and illustrated in the accompanyingdrawings, which disclose the preferred embodiment of the invention, andpointed out in the claims hereunto appended.

Referring to the drawings in deletail, the device comprises a sampler ortrier tube it having an outwardly tapered pointed piercing end ii, theextreme pointed tip l2 thereof being solid for effective piercingoperation while adjacent to this tip is an elongated opening [3 whichallows the inflow of a quantity of bulk material held within acontainer, such as a bag, sack or the like, a portion of the bag, sackor the like being indicated at I 4, and the strands of its weave aredenoted at I5 and I6, respectively. The tube [0 is of straight formationand can be of any desired length for insertion within the bulk of material ll the required distance for sampling of such material, thesample quantity of the material being delivered into the tube throughthe opening I3 therein after penetration of the bulk by the tube andsubsequent withdrawal of such tube from the bulk, as is common in theuse of sampler or trier tubes.

Fixedly held on the tube at the end opposite the tip I2, which end isopen as at I8, is a hand knob or grip I9, it being flattened as at 20 toserve as an indicator side thereto indentifying that side having theopening I3 in said tube while slidably fitted upon the straight extentof the said tube I is a header or crown stock 2I, which is preferablycircular in contour and is rounded upwardly in the direction of the knobI9. The tube has formed therein an annular inset stop shoulder 22 withwhich cooperates a spring ring-like latch 23 fitted within the header orcrown 2I to limit the relative movements of the said tube and header orcrown in one direction, Surrounding the tube Iii is a coiled expansionspring 24 seated against the header or crown 2| and against the knob orgrip I9, and the purpose of this spring is to hold the shoulder 22normally engaged by the latch 23.

Carried by the header or crown 2| are slightly outwardly flared spacedopposed wings or cheeks 25, these coacting with each other to functionas a gauge and also as a guard hereinafter set forth.

Tufted or otherwise anchored within the '1 header or crown 2| are outerand inner series of tines 2B and 21, respectively, these encircling thepiercing end of the tube I0 being grouped about the same. The tines ofthe series are inherently resilient or springy, and normally crowd aboutthe tip I2 of said piercing end of the tube A when disposed inwardlybetween the wings or cheeks 25, this being the normal position.

Embracing the outer series of tines 26 are the yokes 28 and 29,respectively, these being reversely fitted with relation to each other,and are made fast to the wings or cheeks 25 for the overlapping thereofin a horizontal direction, the wings or cheeks 25 being of slightlydifferent lengths with respect to each other so as to have an overlappedrelationship between the yokes 28 and 29 in their reversely extendedpositions inwardly of the said wings or cheeks. The purpose of the yokesis to limit the spread of the outer series of tines 26 in the operationof the device while the yoke 28 functions as a gauge to limit thepenetration or insertion of the outer ends of the tines 26 and 2! whenthe device is brought into a set position against the bag exteriorlythereof when carrying bulk material and thus said yoke functions as agauge, this positioning of the device being shown in Figures 2 and 3 ofthe drawings.

In the use of the device, after the setting thereof with relation to thebag, when the tube I0 is pushed upon, its piercing end II scatters thetines 26 and 2! in that the piercing end II will urge such tines out ofits path of movement when penetrating the bulk of material within thebag, and in doing this the tines 26 and 2'! become active upon thestrands I and I6 of said bag, sack or the like, the outer ends of thetines being carried through the interstices between the strands orwithin the weave thereof, and thus temporarily effecting, through thedisplacement of such strands, an opening in the bag, sack or the likebody for the passing of the tube I0 within the bulk therein for samplingoperation, and without damaging the strands I5 and I6 during suchoperation of the device. Now when the tube II] is extracted or removedfrom the bulk I! of material within the bag, sack or the like, the tines26 and 21 return to normalcy and thus effect the closing of thetemporary opening created within the body of said bag.

The tines 27 are of outward tapered formation 5 and are heavier than thetines 28 which are straight and of pin shank-like formation.

Swingable from the knob I9 at diametrically opposite sides of the tubeexteriorly thereof are spring-tensioned latching arms 30; the tensioningsprings being indicated at 3|, and the pivots are indicated at 32swingingly connecting the said arms to the knob I9. These arms normallyengage with the header or crown 2|, being forced inwardly by the springs3| for such engagement, and in this manner the tube I0 is held againstrelative movement with respect to the header or crown 2I, thus enablingthe engagement of the tines 26 and 27 in the body of the bag, sack orthe like I4 before eifecting the piercing of the latter and the bulk I!of material therein by the tube I 0, in that the piercing end I I iswell within the series of tines 26 and 21 and confined between the wingsor cheeks 25, which is the normal position of the said tube I0.

It is required that the arms be initially moved from contact with theheader or crown 2I when it is desired to operate the tube ID for thepiercing action thereof in penetrating the bag, sack or the like I4 andthe bulk I'I therein.

When the tube In accumulates a quantity of the material for sampling ortesting purposes, by upsetting the device after removal from samplegathering activity thereof the quantity of material collected therebycan be discharged through the open end I8 of said tube for inspectionand test purposes. During the penetrating or piercing operation of thedevice the air within the tube I0 is dispelled through the open end I8,for the infiow of a quantity of material through the slot I3 in thepiercing end II of the said tube.

Through the activity of the tines 26 and 27, the strands I5 and I6 ofthe body of the bag, sack or the like I 4 will become set to normalcy,thus eliminating a permanent opening in the bag, sack or the like, as atemporary opening is created resultant from the insertion of thepiercing end II of the tube IEJ into the bag body for the samplingoperation of the device.

The wings or cheeks 25 are rigid and permanently secured to the headeror crown 2 I, the tube I0 being manually moved relative to the header orcrown 2I and in the use thereof it is pushed inwardly of said header orcrown for the forcing of the piercing end I I through the body of thebag, sack or the like into the bulk I! of material whence a quantity ofthe latter will flow through the opening I3 for the collecting thereofwithin the tube ID to allow inspection or testing of such material.
